Could be any number of things, but the cheapest thing you can try is by buying an additive for your fuel tank that will remove sulfur deposits. My Taurus's needle used to float and not read at all sometimes, 2 bottles of "Techron" later and i haven't had any problems since.
how do u fix a gas needle on a 2004 nissan maxima
Type your answer here... change sending unit located in the gas tank
Then fix it
if the float/needle assembly do not seat properly. the gas will slowly leak past the needle and into the cylinder-then past the rings into the oil. you probably need a carburetor rebuild.

Find the leak, and fix the cause.
Your carburetor is loading up. Or your needle valve is out of place or stuck.

This could possibly be a bad stepper moter in the instrument cluster. If you can solder, it is an easy fix.
The problem is most likely in the float bowl. The float could be bad. The likely cause is the needle valve that is control by the float is stuck, or dirt has gotten between the needle and needle seat. This is an easy fix. Carefully remove the float bowl. The float will be held in place by a pin. Remove the pin, and float. Check that there is no fuel in the float, and that it floats in gas, if not replace. The needle valve will come out with the float, as they are connected by a wire link. Make sure needle vale is clean, and able to move freely inside it's housing. Check the bottom of the housing at the needle seat to make sure it is clean of dirt. Reassemble, and you should be ready to go.
